HI!
I am curently tring to make a overhead first person shooter and after downloading TNT Basic 1.1, I had a look at the scrolling examples and decided to adapt it to my game. However, I already have a simple sprite movement system that uses arrow keys to move the character around the screen, but do I need to get rid of one as they look like they do simmilar tasks, but without the arrow key sprite movement, will my charcter be still in the centre of the screen for the entire game with the scenery moving around it? Not what I want!
Any help or ideas much appreciated.

Your player won't stay in the middle until you specify it to the computer. TNT has nothing already decided ( wich is good! ) such having a hero sprite.

You could use:

Xmap=X-320 >>>320 is half of 640<<<<
Ymap=Y-240 >>>240 is half of 480<<<<
set viewport offset 1,Xmap,Ymap


if you use that, you will have to use a larger canvas so that your viewport doesn't scroll out of it. If you need more help, tell me your e-mail adress and I'll send you and example.
